LUTHER B. BARTH, OF TIFFIN, OHIO.

FERTILIZER-DIVSTRIB'UTER.

Application tiled November-24., 1999, Serial No. 529,705.

To all whom, t may concern Be it knownthat I, LUTHER B. BARTH, citizenof the United States of America, rresiding at Ti'liin, in the county ofSeneca and State of Ohio, have invented certain new and usefulImprovements in Fertilizer- Distributers, 'of which the following is aspecification.

This invention relates to fertilizer' distributers or spreaders ofthecharacter iiven over .the ground to during its adapted to bedischarge the fertilizer therefrom )assage over the ground.

The object of the present invention is to provide an attachment for afertilizer distributer conveyance by means of which the fertilizer maybe more thoroughly pulverized and discharged and scattered'over a.

much wider swath than has heretofore been possible.

It is a further object of the invention to provide an attachment which.may be readily applied to a fertilizer distributor of the beater typewith very little t-rouble and at a very small cost.

Further objects and advantages of the invention will be set forth in thedetailed descript-ion which now follows.

'In the accompanying drawing, Figure l is a partial vertical sectionupon line -i/-g/ of Fig. 3 lof a fertilizer distributer of the beatertype having my invention applied thereto, Fig. 2 is a horizontal sectionupon line .fcir of F ig. l, Fig. 3 is a. rear end elevation, and, Fig.4c 1s a detail View of a' modified form of distributer memberhereinafter described! Like numerals' designate parts in all of thefigures of the drawing.

My attachment is designed to be applied to an yordinary fertilizer"distributer of the beater type, 'comprising the body 5. the rear-vwardly moving slatted bottom 7, ground wheels '7, beater' 8, and drivingmechanism comprisingA the sprocket drive 9 and the spur gear drive l0,by means of which motion is transmitted from the ground wheel 7 to theshaft l1 of 'the beater. So far, the parts described are all well knownreduire no further description.

In carrvinr out mv invention. I secure a hood l2 in such position as toinclose the beater. This hood may be secured tothe body 5 in anv desiredmanner. In`the present instance, I have shown bolts 13 whichSpecification of Letters Patent.

corresponding Patented July 23, 1212. Renewed January 3,1912. serial No.669,235.

pass through the side walls of the hood l2 and through the body 5 andhold the hood firmly in position. ,Rearwardly projecting bars 14 aresecured to the underside of the. body by bolts l5, these bars serving tosupport oppositely rotating distributer members beneath and slightly inthe rear of the beater. The bars 1,4 at their outer ends are secured toblocks 16, these blocks in turn being` secured to a cross bar 17.Hangers 18 extend from the underside of this cross bar and a shaft 19 isjournaled in those hangers. This shaft is driven by a sprocket chainconneet-ion 2O from the heater shaft ll, (see Fig. 3) thissprocket chainbeing preferably incl osed by a guard 2.1 which is held inposition bybrackets 22- "The shaft 19 carries bevel gears 23 which mesh with bevelpinions 24.1 mounted upon the shafts 25 of oppositely rotatingdistributer members- 26. In the form of distributor member shown inFigs. l, 2, and 3, I employ plane disks 27 28 upon their upper faces. Ifdesired, ho-W- ever, other forms of horizontally rotating distributermembers may be employed. Such for instance as that illustrated in Fig.4.-, where the blades 299 are shown applied to -a conica-l body portion27a. While I have shown the blades 28'and 28a as curved, it is apparentthat they may be made stra-ight if desired. Secured within the` hood 12are inclined deiectors 29, there being one of these deiiectors at eachside of the hood. A centrally arranged nose shaped deflector is alsosecured to the inner face of the rear wall of the hood.

The operation of the device is as follows: As the fertilizerdist-ributer is drawn -over the ground in the usual manner, the rotatothe beater in the direction of the arrow a. rllhe fertilizer which iscontained Within in this art and the body 5 and which is fed rearwardlyaga-inst t-he beater by the movement of the bottom 6 in the usualmanner, is thrown rearwardly by the beater and strikes against :the rearWall 12a of the hood 12.' The inclined deflectors 29 conduct the bulk ofthe material Well over the horizontallyl rotating distributor members26, the direction of rotation of said members being indicated by :thearrows b in Fig. deector 30 causes the material to fall well- 4forwardvupon the ldistributer members, itl

2. The nose shapedhaving the radially arranged curved blades'- tion ofthe ground Wheels imparts lrotation rear wall would rail straightdownward and a large portion of it would pass between the distributormembers without touching them.

. The rotation of 'the distrib: r members 26 vuse of the presentinvention,

results in hurling the fertilizer broadcast to the rear of the machine,spreadingiit evenly in a wide swath or path not only directly in therear of the machine, but to some distance upon each side thereon. Ifdesired, an apron 31 may be located in front of the distributor membersto prevent the material from beingl thrown olf at the front thereof.From the foregoing description, it will be seen that my invention is inthe nature of an attachment .which may be readily applied to thefertilizer distributors already in use with little or no alterationthereof. f

lVhile I have shown in the accompanying drawing a. method ofconstructing the device, it is of coursel apparent that many 'changesmight be resorted to as regards the constructing of the framework forsupporting tie vital elements that comprise the invention. Likewise, thenumber of blades upon the distributer members may be varied at will `andthese members may be made of any desired material so long as they are soconstructed as to prevent rusting or corrosion. Furthermore, the methodof driving these distributor members may be varied if desired. Forinstance, instead of connecting them to the beater shaft, they may beconnecteddirect to the ground wheels or driven from any other of themoving parts of the machine. I prefer to make the deA flectors of sheetiron, the surface of which will be polished and smooth, though thesedeliectors may be of other material and their pitch maybe varied at willto direct the material to any desired point upon the face of l therotating distributer members.

A fertilizer distributer constructed in ac coi-dance with the presentinvention has been actually tested by me and whereas the beater type ofdistribu-ter to which my attachmcnt was applied and upon which it wastested, spread the fertilizer material in a path or swath of about threefeet wide before my attachment was applied thereto, said material wasspread in a path or swath from ten to twelve feet wide by the' use ofthis attachment. Furthermore, where the beater alone employed forhurling the material rearwardly. the material is not only noticeablythick-er at the middle of the swath than at` tiay ainfos. but thematerial often passes over the beater in large unscattered bunches,falling thus upon the ground This objectionable result is avoided by thethe swath spread by my invention being u'nifo. throughout its width andfurthermore, every to fall directly particle of the material heiligthoroughly pulverized and scattered -by coming in contact with therapidly rotating distribnters.

From the foregoing facts disclosed by actual test, it will be readilyapparent that much less time will -be required to cover a given areawith fertilizing material by the use of my attachment than would be thecase if said attachment were not employed. Furthermore, this attachmentis well adapted to handle any character of fertilizing material that canbe thrown rearwardly by the beater. The attachment is compara tivelysmall and does not interferewith the ready passage of the machinethrough-gates, doors, or other openings, and if for any rea son it isdesired to remove it,"this may be do'ne by merely removing thefastenings 13 and l5. Furthermore, if the distributer members 2G and thedeflectors are removed and the hood left in place, the hood acts as awind shield to prevent the material from being blown about by the windas it is discharged from the beater, and the rear wall of the hoodcauses the material to drop straight'down upon the ground. Theattachment increases the draft but very little because the only actualresistance to4 the movement of the distributor members is due to theloose fertilizer falling upon them and being thrown therefrom bycentrifugal force.

Vlhile the ele-mentsA shown and' described are well adapted to serve thepurposes for which they are intended, it is to be understood that theinvention is not limited to the precise construction set forth, butincludes within its purview such changes as may be made within the scopeof the appended claims.
